xfs: remove lsn relevant fields from xfs_trans structure and its users
The t_lsn is not used anymore and the t_commit_lsn is used as a tmp storage for the checkpoint sequence number only in the current code. And the start/commit lsn are tracked as a transaction group tag in the xfs_cil_ctx instead of a single transaction, so remove them from the xfs_trans structure and their users to match with the design.
